silicon disulfide
Quick Summary
Silicon disulfide (SiS₂) is a chemical compound with a structure consisting of infinite chains of SiS₄ tetrahedrons that share edges. Each SiS₄ tetrahedron has a central silicon atom bonded to four sulfur atoms. Silicon itself is a nonmetallic chemical element, second only to oxygen in abundance in Earth's crust. It is known for its role as a semiconductor, forming the basis of computer chips and solar cells. While silicon dioxide (silica) is abundant, silicon disulfide is a specific compound with a unique chain-like molecular structure.12
